IPC: B65D47/38
Filed: 1967-05-09
Abstract: 1,152,931. Container closures; opening containers. SOC. D'APPLICATIONS TECHNIQUES ET INDUSTRIELLES S.A. 9 May, 1967 [10 May, 1966], No. 21544/67. Headings B8D and B8T. A perforator cap 11 includes a deformable membrane 12 which carries an element 14 for puncturing a diaphragm 15 covering a container mouth. Initially, the membrane is in a stable convex position as shown in Fig. 1. When it is pushed downwards, the membrane assumes a stable concave position, Fig. 2 (not shown), and the element 14 pierces the diaphragm 15. In subsequent use, the element 14 provides a closure for the aperture produced. In a modification Fig. 5 (not shown), the perforating element is provided with a distribution passage for the contacts of the container.

Title: Improvements in precision casting
Inventor: DUNLOP ADAM
IPC: B22C1/16
Filed: 1949-08-22
Abstract: 669,130. Moulding processes; mould materials. ROLLS-ROYCE, Ltd. Aug. 22, 1950 [Aug. 22, 1949], No. 21790/49. Drawings to Specification. Class 83 (i). In a method of making a mould in which a wax pattern is invested in a refractory material and subsequently melted out, the pattern is given a coating of a fine refractory suspended in a silicate binding liquid without a hydrolysing agent followed by a coating of a refractory damped by a hydrolysing agent, which latter causes gelling of the silicate binder. The coating material containing no hydrolysing agent preferably comprises a fine refractory such as flint powder, alumina, sillimanite, zirconia or mixtures thereof suspended in ethyl silicate and a condensing agent such as piperidine or monoethanolamine. The second coating comprises a fine refractory such as fireclay grog wetted with a mixture of methylated spirits and water. When the ethyl silicate has gelled, the process may be repeated to build up a thicker layer on the pattern before the final investment in a water-borne refractory or in a suspension of a refractory in a liquid containing ethyl silicate and having a gelling time of about eight hours. Before the first-mentioned coating, the pattern may be sprayed with a mixture of fine refractory suspended in soap solution, sodium silicate and hydrochloric acid, the latter serving to condense the sodium silicate and bind the coating. After the wax pattern has been melted out, the mould is heated to approximately 1000‹ C. before casting. Specification 635,959 is referred to.

Title: Improvements in or relating to coin freed mechanisms
Inventor: TOLL CECIL ALBERT
IPC: G07F15/12
Filed: 1960-06-22
Abstract: 921,721. Coin-freed mechanisms. ALBERICE METALS Ltd. June 1, 1961 [June 22, 1960], No. 21864/60. Class 27. A coin-freed mechanism for controlling the condition of an electric switch 19, Fig. 2, comprises a first member 30 having a screw-threaded portion co-operating with a screw-threaded bore in a second member 31; means for rotating one of the members relative to the other in response to the feeding of a coin or token into the mechanism for moving the other member from a first position, in which a controlled apparatus such as a refrigerator, heater, television or radio receiver, connected to the mechanism is in one state, to a position in which the apparatus is in a second state, and a timer motor 23 for rotating the said other member relative to the said one member towards its first position. A shaft 4 is rotatable by a knob when a coin of correct thickness is inserted through a slot into a recess 2, Fig. 1, in a disc 3 disposed between a pair of plates, a pawl 5 ensuring that when the disc is rotated, the coin is the correct diameter. Rotation of the shaft 4 rotates the first member, which is in the form of a screwed rod 30, to axially move the second member, which consists of an internallythreaded gear 31, from an end position engaging the switch 19. When the controlled apparatus is used, the motor 23 rotates a gear 33 to return the gear 31 to its original position and re-engage the switch. An indicator 34 records the total credit and when the maximum credit, 35 coins in the present embodiment, is exceeded, the gear 31 runs off the rod 30 so that the insertion of further coins is not credited. A spring 37 ensures re-engagement of the gear on the rod when the controlled apparatus is used. In a further embodiment, the coin-receiving means is of the type used in domestic gas meters suitable for coins of different values. An inserted coin acts as a clutch between a manually rotatable shaft and a shaft carrying a gear engaging a long gear in turn engaging an internally threaded gear on a screwed rod so that rotation of the shaft moves the latter gear along the rod away from a switch controlling the apparatus. When the apparatus is operated, a time motor rotates the screwed rod to return the gear to its original position to actuate the switch and prevent further operation of the apparatus. A counter indicates the amount of credit, the internally threaded gear running off the rod when the maximum permissible credit is exceeded.

Moulding processes; moulds; flasks; clamping flasks and moulds.-Relates to a method of sealing the joint between the halves of sand or like moulds used, for instance, in casting electrically heated or thermit steel about adjacent rail ends and consists in applying additional pressure to the mould material after the half moulds have been assembled thus avoiding the use of external luting or of asbestos strips soaked in molasses &c. arranged in the joint. Each flask 1 is supported, while the sand is rammed about the pattern X, by spacers 7 on the board 6 so that the parting face 8 projects. The half moulds are then assembled and forced together by clamps 15, each having a screw 17 in a fixed bar 16 engaging a sliding bar 20. In order to compress the sand at the edges of the parting effectively, flanges 10 are formed on the inside of the flasks. The sides 2 of the flasks may be reinforced and connected by angle iron 4 and the end 3 may be closed.

Abstract: 1363223 Integrated circuits TOKYO SHIBAURA ELECTRIC CO Ltd 10 May 1973 [13 May 1972] 22322/73 Heading H1K In the manufacture of an integrated circuit a semi-conductor wafer, e.g. of low resistivity Si, 20, carrying a higher resistivity epitaxial layer 20a, is provided with grooves 22 by etching through a mask 21, e.g. of silicon nitride, and a dielectric layer 13 is formed within the grooves 22, preferably by oxidation. The mask 21 is then removed and a layer 14 of semi-conductor is vapour deposited. The layer 14 is polycrystalline where it occupies the grooves 22, and may be polycrystalline or monocrystalline over the exposed surfaces 23 of the wafer. A second dielectric layer 12 of silicon dioxide or nitride is formed on the layer 14, and a support substrate 11, e.g. of polycrystalline Si, is deposited on the layer 12. By a combination of etching and lapping the wafer 20 is removed, together with parts of the dielectric layers 12, 13, and the intervening polycrystalline layer 14, to result in the situation shown in Fig. 2D, wherein there are provided mutually isolated semi-conductor islands each of which is surrounded by a dielectric layer 12 and includes a bottomless dielectric wall 13.

Abstract: 1,041,948. Frequency digitizers. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 26, 1965 [May 26, 1964], No. 22348/65. Heading G4H. The excitation function is produced from vocal signals by apparatus which includes means for eliminating the effects of spurious zero-crossings caused by harmonics. The signals are passed through a low-pass filter 2, Fig. 6 (not shown), to a zero-crossing detector 3. Counter 5 is continuously advanced by clock pulses and is reset by detector 3, the output of which also opens gate 6 to pass the contents of the counter to register 11. If no spurious zero crossings have occurred adder/subtractor 9 and decision circuit 10 determine that the sum of the contents of registers 11 and 12 is significantly greater than the contents of register 13 and a shift signal is produced to transfer the contents of each register to the next, register 13 feeding mean value circuit 8. If a spurious zero-crossing occurs, the sum of the contents of registers 11 and 12 is approximately the same as the contents of register 13, no shift signal is produced and the contents of 12 are replaced by the sum from 11 and 12, the next digitized value subsequently being substituted in 11. Circuit 8 includes a shift register 14 containing the last ten digitized values, a register 16 containing the sum of the last ten values (s), adder 15 deriving the new sum (s+tn-tn-10), and a divider 17 dividing the sum by 10 to obtain the mean value.
